Washington state’s Legislature has passed a bill to allow sales of marijuana concentrates like hash oil at state-licensed pot shops.

House Bill 2304 also tweaks Washington’s legal marijuana law to allow marijuana processors to sell to other processors. For example, a processor who specializes in making marijuana extracts could provide those to bakers who might use them in brownies.

The bill, which required at least a two-thirds vote to amend Initiative 502, passed the Senate on a 42-7 vote Thursday, shortly after passing the House on a 91-7 vote

The initiative itself allowed the sale of dried marijuana and marijuana-infused products, but not of marijuana extracts or concentrates. The bill allows people to buy up to 7 grams of those potent products in addition to their one-ounce limit of dried marijuana, 16 ounces of infused solids or 72 ounces of infused liquids.
